The aim of the present investigation was to discover the genetic relationships of 2009 pandemic novel influenza A/H1N1 virus (NIV) external antigens Hemagglutinin (HA) and Neuraminidase (NA) with other influenza viruses by performing phylogenetic, comparative and statistical analyses. Phylogenetic trees
